42. Parameter : 1 - An unknown factor that may vary over a certain set of values. This word occurs in defining frequency distributions (e.g. `population parameter`) or in models describing stochastic situations (e.g. `regression parameters`). The statistics that we determine from the samples of a population are estimates of the unknown parameters. 2 - A summary measure of the observations comprising a population (e.g. a mean, median, etc.) as contrasted with the analogous summary measure for a sample referred to as `statistic`.3 - See 8550.
